Should kids go barefoot for school?

@SW-User We did for marching band once to focus on how we were moving our toes, etc. and practice doing that better. Also, many people wore flip flops often, so just took them off to practice marching when it was allowed. (If shoes were required, they'd just change into them and go back to sandals for the rest of the day if there was school, so a lot of us didn't wear socks anyway.) As for gym, one year it included swimming, so obviously we were barefoot for that, but I've read a lot about schools doing other parts of physical education barefoot.
